Decomposed Granite Landscaping Installation

Decomposed granite is made up of granite aggregates a 1/4″ or smaller and sometimes decomposed granite is so fine that it resembles sand. Decomposed granite is the least expensive way to pave a patio, walkway, or driveway. decomposed granite provides a natural, rustic look and is available in subtle hues of gray, tan and brown.

Types of Decomposed Granite

decomposed-graniteLoose Decomposed Granite – Loose decomposed granite, the least expensive type, is simply the granite aggregates, without any additives. Uses for loose DG include:

  1. Landscape mulching
  2. Garden paths
  3. Patios
  4. Play areas and sports courts

Since it is not a solid surface, loose decomposed granite provides excellent drainage. Once compacted, a patio or walkway covered with lose decomposed granite will be fairly hard. However, loose decomposed granite is easily affected by erosion and will need to be filled in often. Avoid laying loose decomposed granite near your house because it is easy to track inside, which can be quite messy and may damage hardwood flooring. During the winter, when rain is frequent, loose decomposed granite paving will become mushy and muddy.

Stabilized Decomposed Granite

Stabilized decomposed granite has a stabilizer mixed in with the granite aggregates. Compared to loose decomposed granite, stabilized decomposed granite is more expensive, but it’s still less expensive than, decorative concrete and natural stone. Once spread and compacted, decomposed granite with a stabilizer will look similar to loose decomposed granite, with the top layer appearing loose and organic. However, stabilized decomposed granite will be less susceptible to erosion. thus it has a longer life span and requires less maintenance. Many landscaping companies will deliver decomposed granite with a stabilizer already mixed in.

Decomposed Granite with Resin

This is the most expensive of decomposed granite. Resin is added to the decomposed granite, creating a surface similar to asphalt. Sometimes called poly pavement, decomposed granite with resin is the strongest and most durable decomposed granite option, making it great for driveways and high traffic areas. The look will not be as natural as loose or stabilized decomposed granite, but it will be much more durable. Pavements made with decomposed granite and resin will not erode or be tracked away. One downside to selecting the resin option is that the drainage is nowhere near as good as loose or stabilized decomposed granite.

Alternatives to Resin

A few products that will help keep your mulch sealed temporarily are available and would keep you from permanently sealing your decomposed granite. One is Mulch lock and works on other types of mulch for your landscape.

Laying decomposed granite is a fairly quick process…

  1. First, the area where the decomposed granite paving will be laid should be excavated.
  2. Then, a weed barrier, such as landscaping fabric, should be laid down and landscape edging should be installed around the perimeter.
  3. Next, the decomposed granite will be placed and compacted. At this point, your patio, walkway or driveway is ready to be used. Depending on the type of decomposed granite you installed you may need to rake and replenish the surface periodically. For this reason it is good to keep some extra decomposed granite of the same color on hand.

Keep in mind, when you first install the decomposed granite it will have a darker color but will lighten up over time for a more sandy color.
